Clarification of impact wear mechanisms of the DLC coating based on its phase transformation after cyclic impacts by using Raman spectroscopic analysis Proposal of an empirical-based deformation-wear transition map of DLC coating under cyclic impacts in order to graphically distinguish between the plastic deformation and impact wear of DLC coating as well as to predict its transition points for future design purposes. Introduction to the suitability of DLC thin films for industrial needs and its tribological properties for sliding contact. Descriptions of impact wear of metals and DLC coatings under severe wear conditions based on the previous studies. Stating the main purposes of this dissertation.
